My present invention relates to a faucet of the packingless and seat-less type, and has for its object the production of an efiicient and simple structure, comparatively inexpensive to manufacture.

One of the advantages of my faucet is that the operating plunger and casingcontacting portions are protected against leakage, corrosion' and sticking by a fluid-tight metallic self-conforming fluid-pressure expansible ring, and therefore, no packingis required Where the operating plunger contacts with the casing.-

Another advantage in my faucet is that the expansibl'e "passage-closing member. is constantly under fluid pressure against the walls of the faucet body chamber and therefore automatically self-conforming theret0,[thus eliminating regrinding, which is necessary in "most valves now in use.

' Another advantage in my device is that the amount of force required to turn the stem and move the passageclosing means to closing position, is always the same, whereas in most valves of this type where the seats or Jfriction surfaceshave become worn and'there is no provislon for automat cally compensatingthe'refor, 1t 1s necessary to seatthevalve with increasing force 'asthe parts become W wornin order to prevent leakage.

Still another advantage of, my valve is'tliat even though it remains unused for a long time, the fluid pressure expansibleypa'ssage closing meansalso acts as a cleaning member,

" when'the valve is placed in use, for the interior of the casing,and any sediment-or corrosi'on that may have accumulated in the path y of said closing. means is shaved or scraped as uponthe-moving'of-said closing means. 1 Other objects and advantages ofthe invention will appear as the description proceeds; and while herein details-of the invention are described, the invention is i ot'lim-' ited to these, since many and-various changes ma be made without deartin fromthey p b casing-'12 by means of a nut22, -wh1ch 1s shown -in Figs. 1 and 2.

F ig. (Sis a sectional view on the line 66, Fig. 1, looking in the direction of the arrows.

, My valve is shown in Figs. 1 and 2 as comprising a housingor casing'in two parts, to wit: an upper part 11 and a lower part 12,

which are at 13. i

The lower part 12 of thecasing has therein a fluid inlet passage 14 and a fluid outlet passage-15, and contains at the middle part thereofa valve mechanismchamber 16;

an inlet and outlet closing means for said shown as threadedly connected thereof at 18, and serves as a valve carrier.

' The valve proper consists of. an expansible metallicsplit ring 19, which is shown in Figs. 0 1, 2 and 5and has thereon, at the upper end thereof, an inwardly extending flange 19a, 1111a,, encloses another expansible ring 20,

The split in said ring 19 extends through said flange 19a, and the split in, said ring 20 .is staggered with relation'tothe split in said .llllg 19, thereby producinga tight, closing of v the valve19, 20. r a

The flange 19a of saidring 19 fits under an annular flange 2l on said valve carrier 17, and said ring 19 issretainedin contact with the inner cylindrical surface of said lower 19 is retained in position. and kept from fall-. ing down by means of a flange 23 on said A shoulder 24 at the lower end of the valve carrier 17 limits the position of said nut 22 and prevents it from binding said ring 19 endwise thereof, the depth or height of said ring 19 being slightly less than the distance from said flange 21 to said shoulder 24, as shown in Figs. 1 and 2, thereby allowing said ring 19 freedom of motionlengthwise of said valve carrier 17 Openings 25, which are shown in Figs. 1 and 2, are provided in said nut 22 by said flange 23, by means of which the fluid passing through said casing 1112 may enter a chamber 26 which is enclosed by flange 19a, said ring 20 and the upper edge of said nut 22.

The interior of said upper casing 11 has secured thereto a liner 27, which is threaded into said casing at 28and has therein a pair of vertically positioned guideways 29, which are shown in Figs. 1, 2 and 3, and receive therein a pair of guides 30, which are provid ed on said carrier 17, whereby said carrier 17 is prevented from rotating with relation to said casing 1112 when said carrieris actuated by a feed screw 32, as hereinafterv described.

A closure operating stem 31 terminates at the lower end thereof in said feed screw 32, which is shown in Figs. 1 and 2'as threadedly engaging the opening 18 of said valve carrier 17, thereby actuating said carrier and in cooperation with said guides 30 moving said carrier lengthwise the axis thereof; the upper end of said stem 31 extends through said casing 11 and may be provided with any 1'0- tating means such as a hand wheel 33, Whereby said stem with said feed screw 32 thereon may be rotated. r

The stem 31 has thereon an enlargement 34: to contact with a part of the'interior of said casing 11 as at 35, to prevent leakage through the upper end of said casing 11 past said.

stem 31.

A spring 36 is provided to keep said e11- largement 3 1 in contact with said part 35;

said spring 36 encompasses the upper end of said stem 31 and 1s posltloned in a housing or chamber 37 formed at the upper end of said casing 11; one end oi said spring 36 abuts against the lower end of said chamber 37 and the other end thereof presses on said handwheel 33 thereby drawing said stem 31 with said enlargement 34; thereon upwardly and pressing thelatter into contact with said part 35.

In the modification shown in Fig. 5 the nut 22 is omitted and said split rings 19 and 20 are retained in position by a pin 38 passing through the lower end of said valve carrier 17 transversely to the latter, the ends of said pin 38 extending under said rings 19 and 20, thereby retaining the same in position.

To prevent leakage of fluid through the slit 19b in said flange 19a of said ring 19, I provide a slitted sector of an annulus 39, which is secured to said flange 19a by rivets 10 in a recess 41 provided in the top of said flange 19a for receiving said sector 39 therein.

The slit 397) of said sector 39 is stag ered with relation to said slit 19b of said flange 19a, thereby preventing leakage therethrough.

It is evident that by the use of the split rings 19 and 20, the-former with the split flange 19a thereon, the pressure of the fluid passing through said casing 11 12 is employed to maintain sufficient contact between said rings 19 and 20 and between said ring 19 and the interior of said casing 12,,also between said flange 19a with said sectory39 thereon and the underside of said flange 21, to prevent leakage of fluid therethrough.

The pressure of said contact is directly pi-o portional to the pressure of said fluid.-

The assembly of my device is asrfollows:

The valve carrier 17 is first assembled by placing the rings 19 and 20 inposition thereon and connecting the nut 22 to theend of said carrier 17 The casing 11 is heldupside down with stem 31 in position, after which the spring 36 is placed in chamber 37 and compressed between the end of said chamber and wheel 33, which is connected to the outer end of stem 31 by a nut 11 and a thread 42 at the end of stem 31. The feedscrew 32 on stem 31 is then connected to the upper end 18 of said valve carrier v17.

The assembled passage closure is then slipped into the casing 12 and'the casings 11 and 12are screwed together at 13.

Many changes maybe made. in the details of my packingless andseatless valve, without departing from the main scope of my invention, and parts of my inventionl nay be used Without other parts.

. I do not, therefore, restrict myself to the details of my packingless and seatless valve as shown in the drawings, but I intend to include also all mechanical equivalents and obvious modifications of the same within the scope of my invention. 7 1
